"Lost Supper" promo poster

A few blogs ago, someone posted the new official Lost Season 6 promo poster. It is obviously set to look like The Last Supper by Davinci, but careful examination will send your imagination into a tizzy. The most interesting thing I noticed, however, is that there are two skulls in the sand. Adam and Eve anyone? You can see it here: http://lostpedia.wikia.com/wiki/File:Lost_season_6_cast.png
